| Deposit | A SERIES OF PROSPECTS ALONG A N-TRENDING VEIN SYSTEM IN SILTSTONE THAT BEARS N45E AND DIPS IRREGULARLY. SAMPLE 2838 WAS A BRECCIATED AND SILICIFIED PORTION OF A VEIN WITH PYRITE, ANTIMONY, AND POSSIBLY AG. SAMPLE 2839 WAS TO THE NORTH OF THE FIRST ONE BY ABOUT 300 YDS AND CONTAINED VISIBLE PYRITE AND OTHER SULFIDES IN A QUARTZ VEIN AND IN THE ADJACENT SILTSTONE HOST ROCK. |
